WARNING
Read this manual completely and observe all warning labels on the machine. Oliver Machinery has made
every attempt to provide a safe, reliable, easy-to-use piece of machinery. Safety, however, is ultimately
the responsibility of the individual machine operator. As with any piece of machinery, the operator must
exercise caution, patience, and common sense to safely run the machine. Before operating this product,
become familiar with the safety rules in the following sections.
 Always keep guards and covers in place and in proper operating condition.
1. If you are not properly trained in the use of a planer do not use until the proper training has been
obtained.
2. Read, understand and follow the safety instructions found in this manual. Know the limitations and
hazards associated with this machine.
3. Make certain that the machine frame is electrically grounded and that a ground lead is included in the
incoming electrical service. In cases where a cord and plug are used, make certain that the
grounding plug connects to a suitable ground. Follow the grounding procedure indicated in the
National Electrical Code.
4. Wear an approved safety shield, goggles, or glasses to protect eyes. Common eyeglasses are only
impact-resistant, they are not safety glasses.
5. Before operating the machine, remove tie, rings, watch and other jewelry and roll up sleeves above
the elbows. Remove all loose outer clothing and confine long hair. Protective type footwear should
be used. Where the noise exceeds the level of exposure allowed in Section 1910.95 of the OSHA
Regulations, use hearing protective devices. Do not wear gloves.
6. Keep the machine guards and covers in place for every operation. If any guards and covers are
removed for maintenance, DO NOT OPERATE the machine until the guards and covers are
reinstalled.
7. Keep the floor around the machine clean and free of scrap material, saw dust, oil and other liquids to
minimize the danger of tripping or slipping. Be sure the table is free of all scrap, foreign material and
tools before starting the planer. Make certain the work area is well lighted and that a proper exhaust
system is used to minimize dust. Use anti-skid floor strips on the floor area where the operator
normally stands and mark off machine work area. Provide adequate work space around the machine.
8. Maintain a balanced stance and keep your body under control at all times.
9. Before turning on machine, remove all extra equipment such as keys, wrenches, scraps, and cleaning
rags away from the machine.
10. Give the work you are doing your undivided attention. Looking around, carrying on a conversation,
and “horseplay” are careless acts that can result in serious injury.
11. Before performing any service, maintenance, adjustments or when changing knives disconnect the
machine from power source. A machine under repair should be RED TAGGED to show it should not
be used until the maintenance is complete.

4
12. Do not plane boards with loose knots, nails or any foreign material in the workpiece. Irregular, or
warped stock should be jointed first on one side before planing a parallel surface.
13. If the operator leaves the machine area for any reason, the planer should be turned "off" and the
cutterhead should come to a complete stop before their departure. In addition, if the operation is
complete, they should clean the planer and the work area. NEVER clean the planer with power "on"
and never use hands to clear sawdust and debris; use a brush or air hose.
14. Use only genuine Oliver Machinery factory authorized replacement parts and accessories; otherwise
the warranty and guarantee is null and void.
15. Do not use this Oliver planer for other than its intended use. If used for other purposes, Oliver
disclaims any real or implied warranty and holds itself harmless for any injury or damage which may
result from that use.
16. Do not operate this machine while under the influence of drugs, alcohol, or any medication.
17. This machine is deigned for planing wood products only. Do not use to plane any kind of substance
other then wood.
18. Never start the planer while a workpiece is in contact with the cutterhead or knives.
19. Always feed workpiece against the rotation of the cutterhead.
20. Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
 Lead from lead-based paint.
 Crystalline silica from bricks and cement and other masonry products.
 Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals, work in a well-ventilated area, and work with approved safety
equipment, such as those dust masks that are specifically designed to filter out microscopic particles.
Familiarize yourself with the following safety notices used in this manual:
CAUTION: (This means that if precautions are not heeded, it may result in minor or moderate injury
and/or possible machine damage)
WARNING: (This means that if precautions are not heeded, it could result in serious injury or possibly
even death).

Machine Preparation and Setup
WARNING!
The equipment used to lift this machine must
have a rated capacity at, or above the weight
of the planer. Failure to comply may cause
serious injury!
The planer can be lifted from over head using
slings and the two lifting eye bolts (A, Figure 1).
There are two threaded holes for the eye bolts.
One is located in the right front corner and the
other is in left rear corner. Thread the eye bolt
into the hole at least half way and tighten the nut
(B, Figure 1).
Remove the eye bolts and save in case the
machine needs to be moved in the future.

7
Machine Preparation and Setup (cont’d)
Thread leveling bolts (A, Figure 2) into holes in
the four corners of the planer base. The planer
must be positioned on a smooth, level surface.
Install the leveling pads (B, Figure 2) under the
four corners of the planer.
Clean all rust protected surfaces with a
commercial solvent. Do not use acetone,
gasoline, lacquer thinner or any type of
flammable solvent, or a cleaner that may
damage paint. Cover cleaned surfaces with
WD-40 or a 20W machine oil.
Place a level on the table of planer and adjust
leveling bolts until the machine is resting level.
Tighten the hex nuts (C, Figure 2) against the
base of the planer to keep the leveling bolts from
turning.
Electrical Connections
WARNING!
Electrical connections and wiring must be
done by a qualified electrician. The machine
must be properly grounded. Failure to
comply may cause serious injury!
This planer is available in both 1-Phase and 3-
Phase versions.
 Electrical Connections for a 3-Phase Unit
This planer is 3-Phase, 220V/440V pre-wired
220V. If you need to switch the planer from
220V to 440V have a qualified electrician make
the changes.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the machine.
1. Disconnect machine from power source!
2. Remove screws that secure the cover to
connection box.
3. Insert the power cable through strain relief,
and attach the wires to terminals.
4. Re-install connection box cover. With 3-
Phase power verify in-feed roller is rotating
in the correct direction. Lower table
completely. Connect planer to the power
source and push the “ON” button to start the
planer. Crouch down to view in-feed roller
from the front of machine. The top of in-feed
roller should be rotating down towards you
in such a manner that it would pull a piece of
wood into the planer. If it does not,
disconnect machine from power source and
reverse any two incoming power leads.
5. When wiring is completed, tape all power
box joints to keep out dust.
 Electrical Connections for a 1-Phase Unit
This planer is 1-Phase, 220V only.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the machine.
1. Disconnect machine from power source!
2. Remove screws that secure the cover to
connection box.
3. Insert the power cable through strain relief,
and attach the wires to the terminals.
4. Re-install connection box cover.
5. When wiring is completed, tape all power
box joints to keep out dust.

8
Dust Chute Assembly
Mount the dust chute (A, Figure 3) to the planer
hood with eight M6x10 hex head screws (B,
Figure 3). Make sure the dust collection system
has sufficient capacity and suction for your
planer. Always turn on the dust collection
system before starting the planer.
Table Roller Handle Assembly
Thread the handle (C, Figure 4) into the hub.
Handwheel Assembly
Line up the key on handwheel shaft with the key
way in the handwheel. Slide the handwheel (D,
Figure 4) into place and secure with knob (E,
Figure 4).
Control Panel (figure 5)
F. Emergency Stop Button: Stops all
functions of machine, but the planer still has
power. To reset rotate switch clockwise until
the button pops out.
G. Main Motor: Starts rotation of cutterhead.
Will not work if the “Emergency Stop” switch
is engaged, or hood is open.
Changing Feed Rate
The planer has two selectable feed speeds that
feed stock at 20 and 30 feet per minute. To
adjust speed, move lever (H, Figure 5) until it
clicks into place. Change feed speed only
while the feed system is RUNNING!
Table Roller Adjustment
Loosen the handle (I, Figure 4) and move the
table rollers up, or down by raising, or lowering
the handle (C, Figure 4). When you reach the
desired position tighten the handle.
The rollers are usually set higher when planing
rough stock. When planing smooth stock the
table rollers should be set slightly above, or flush
with the table.

9
Raising and Lowering Table
Turn the handwheel (A, Figure 6) clockwise to
raise the table. One revolution equals 1/16”.
Table Stop
The socket head cap screw (B, Figure 6) acts as
a stop and prevents you from running the table
into the cutting and feeding assembly.
Opening Hood
Turn the locks (C, Figure 6) clockwise to open
the hood. The hood will open automatically.
Use the handle (D, Figure, 6) to shut the hood.
Calibrating the Thickness Scale
The following sections will describe the use of a
calibrating board. The calibrating board should
be made of a hardwood and have one side that
has been run through a jointer.
1. With the planer turned “OFF – cutterhead
NOT spinning”, place your calibrating board
jointed surface down on the table and slide it
into the machine.
2. Use the handwheel (A, Figure 6) to raise the
table so that the in-feed roller is about 1/16"
above the calibrating board.
3. Remove calibrating board from planer and
turn the planer “ON”.
4. Turn the handwheel clockwise one complete
revolution to raise the table and run the
calibrating board through the planer.
5. Repeat Step 4 until the planer removes the
entire top surface of your calibrating board.
6. Measure the thickness of the board using a
pair of calipers.
7. Adjust the pointer (E, Figure 6) so that it
reads the measured thickness by loosening
the screw that holds it in place.

10
Digital Readout
The digital scale equipped with your 4455 ,22”
planer can serve many applications,however for
wood planing we need only concern ourselves
with the ON/OFF, SET, and mm/in buttons.
When set properly the digital readout will display
the thickness of the finished product.
Calibration: In order to calibrate the unit first
run a board through the planer and measure the
finished thickness with a set of vernier calipers.
This is the number to be entered into the display
unit. At this point turn the unit on by pushing the
ON/OFF button. Now press the mm/in button to
set the unit to American standard or the metric
system.
1. Press and hold the SET button until the ‘+’
sign starts to flash and immediately release
it.
2. Cycle the set button by pressing it until the
‘+’ sign remains on.
3. Press and hold the SET button until the
second zero to the right of the ‘+’ plus sign
starts to flash and immediately release it.
4. Cycle the SET button by pressing it until the
number reads the correct whole number
taken with the vernier calipers and
immediately release the button.
5. Press and hold the SET button until the zero
to the right of the decimal point starts to
flash.
6. Repeat steps 4 and 5 until the last digit in
the 0.001 place is entered.
7. Press and hold the SET button until the SET
on the display starts to flash and
immediately release it.
8. Press and release the SET button one final
time to complete the calibration.
Note: Do not turn the device off. If you do
you will have to re-calibrate the unit.
Battery: When the display begins to flash the
battery should be replaced. The battery is to be
replaced with a SR144 (or equivalent) and can
be found at most pharmacies or grocery stores.
When replacing the battery the positive side of
the button cell must face out.
